Product details
Introduction
Phosphoric Acid Tri-n-butyl Ester is a colorless, odorless, transparent oily liquid with a flash point of 193°C, a boiling point of 289°C (101KPa), a viscosity of 3.5 to 12.2 centipoise, and a refractive index of 1.4226 (20°C).
The product is soluble in ethanol and other common organic solvents, and slightly soluble in water. The solubility of water in this product is 7% (25°C). But as the temperature increases, it will gradually hydrolyze.

Application
1. Phosphoric Acid Tri-n-butyl Ester can be used as a gas chromatography stationary liquid, a solvent for nitrocellulose and ethyl cellulose, a plasticizer, a rare earth metal separation agent and an organic synthesis intermediate
2. It has a good inhibitory effect on acrylate, methacrylate, acrylic acid, acrylonitrile, styrene, butadiene, and its inhibitory performance is better than that of phenols.
3. Used as an extractant for metal complexes, a plasticizer for nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride, and a solvent for paints, inks and adhesives
4. It is used as the main plasticizer of nitrocellulose, cellulose acetate, chlorinated rubber and polyvinyl chloride. It is also commonly used as a solvent for coatings, adhesives and inks, defoamers, antistatic agents, and rare earth element extractants. . The LD50 of rats is 3000mg/kg.
5. Nitrocellulose and cellulose acetate solvents, defoamers, heat exchange media, plasticizers, extractants. Cobalt, iridium, manganese, molybdenum, palladium, rhodium, nickel, uranium and tungsten are extracted with gas chromatography stationary liquid (maximum temperature 120℃, solvent is ether), and molybdenum is determined by colorimetric method. Organic Synthesis.
